How Long

I have been trying to keep knitting the baby blanket that I'm currently working on and figure out how long to make it. It is 32 inches wide and right now 34 inches long. I thing I'm going to go for 36, but I still fill like it is to short will see when I get there. I have more yarn and want to make more blankets, but one baby doesn't need that many. I'm going to have to thing on other things to do with the yarn.
